Provided is a small size optical system having functions of a luminous flux splitting optical system or those of a luminous flux integrating optical system and functions of a fly's eye integrator. The integrator is provided with two surfaces. A first surface (111) is composed of a first unit surface, i.e., a positive refractive surface, and a second surface (113) is composed of a second unit surface, i.e., a positive refractive surface. Prescribed n number of second unit surfaces (113a, 113b) correspond to a prescribed first unit surface (111a). Light which entered the n number of second unit surfaces and parallel to the optical axis of the prescribed first unit surface is collected to the center of the prescribed first unit surface. The n number of second unit surfaces are arranged not to be adjacent to each other on a refractive surface having substantially the same diffractive power as that of the refractive surface of the prescribed first unit surface.

Provided is a microscope for focusing by inserting a split prism (5) at a focusing support time. The image of an iris stop (30) is branched into such two images by the angle deflecting action of the split prism (5) as are individually shifted and focused at symmetric positions across the optical axis of the microscope. These two branched images of the iris stop (30) are further focused on an objective lens (23) through a beam splitter (22) by the focusing action of a lens (21). The operation unit of a vertical motion device is operated to move an optical system up and down so that the images of a focused pattern (16) are viewed to move in opposite directions from each other in the field of view. At the focusing time when the focal position of the objective lens (23) is focused on a sample face (24), the images of the focused pattern (15) look in the registered state. Thus, the focusing action can be made highly precise without being restricted by the magnification or NA of the objective lens.

A surface inspection apparatus includes: a light source unit that emits a divergent light flux of predetermined linearly polarized light to be used to illuminate a test substrate; a first optical member that allows the divergent light flux of the predetermined linearly polarized light to enter therein with a predetermined angle of incidence and then guides a light flux to the test substrate; a second optical member that allows a light flux from the test substrate to enter therein, emits a convergent light flux thereof with a predetermined angle of emergence and forms an image at a specific surface; an extraction unit that extracts linearly polarized light in the convergent light flux from the second optical member, which is perpendicular to the predetermined linearly polarized light; a light-receiving unit that receives an image of the test substrate formed via the second optical member and the extraction unit; and at least one polarization correcting member disposed within a light path extending between the light source unit and the light-receiving unit, which corrects a disruption of a polarization plane attributable to the first optical member and the second optical member.

An apparatus of testing a semiconductor element applies pulsed voltages synchronized with each other, respectively, to a gate and a drain of a semiconductor element being tested and measures current flowing through the semiconductor element in response to the pulsed voltages thus applied. The testing apparatus produces pulsed I-V characteristics considering the influences of self heating and surface energy levels of the semiconductor element and RF swing along a load line during large signal operation.

An image reproduction apparatus with a plurality of disk players which concurrently perform play operation so as to produce a plurality of division video format signal concurrently. The video format signal are combined into a signal/final video format signal. The respective frame numbers extracted from the respective division video format signals are compared with the corresponding designated frame numbers. When the extracted frame number and the designated frame number do not coincide to each other, the corresponding division video format signal is ignored in the synthesis operation for producing the final video format signal.

An integrated circuit device includes a substrate, circuit elements on the substrate, and an electrically conductive thermoplastic resin substance electrically connecting the circuit elements on the substrate. Therefore, since variations in the configuration of the thermoplastic resin are quite small relative to those of interconnecting wires, variation in parasitic inductance due to variation in the configuration of the connections is reduced and the uniformity and the reproducibility of the high frequency characteristics of the integrated circuit device are enhanced. A method for fabricating an integrated circuit device includes forming circuit elements on a substrate and forming an electrically conducting thermoplastic resin substance electrically connecting the circuit elements.
